The project is a collaboration between Hasselt University, University of Antwerp, Antwerp University Hospital and University of Regensburg.

Together, these partners will investigate the (Cost-) effectiveness of a blended physiotherapy treatment, including the use of a smartphone application, compared to the classic physiotherapy treatment that has already proven its effectiveness in the past.

The specific form of somatosensory tinnitus we are investigating in the current project is present in about 25% of people with tinnitus, which means that it affects over 200.000 people in Flanders and 10,5 million Europeans. Participants will be recruited in the TINTRA tinnitus clinic of the Antwerp University Hospital. The study was approved by FAMHP and the ethical committee on December 6th, 2021 (Eudamed: CIV-21-09-037760).

The project officially started on October 1st 2021 and will continue for four years. During the project, useful information for people with tinnitus and for healthcare providers will be shared on this website. At the end of the project, the results of our study will be shared here as well.
